Application filed November 8, 1920. 4vSerial No. 422,487.

T 0 all wiomz't may concern Be it known that l, SAMUEL BnnLoTTi, a citizen of the United States, residing at St. Louis, Missouri, have invented certain new and useful Improvement in Metallic Containersf of which the followingy full, clear, and exact description, such asl will enable .others skilled in the artto which it'apsticking or binding. Heretofore, containers of this type 'were provided with removable tops or covers having straight annulailflanges adapted to be fitted over the' annular flange ron the container.` Itis'obvious thatA in order to retain the cover in position.

.Y it has to vform a tightly fitting joint lwith the wall of' therontainer. Then it is desired to open the container of this type, the cover has to be removed forcibly, usually by prying itopen ywith-some instrument applied to the edge of the cover. In some instances a 'member pivoted to tlie'container is used vto bear against the edge of the cover and pry This practice distorts the shape of the cover sothat it no longer forms an aii` tightjoint with the wall of the container,

thus permitting the air to enter said conalso'serves thel purpose of maintaining an air tight joint 'between' said container and" tainer, drying out the contents and thereby causing deterioration and destroying the usefulness of the container.

Further objects of this invention are to provide a metallic container which is simpley but strong and inexpensive to manufacture; to provide a container and a cover therefor which can be easily and quickly removed without the use of force or any kind of tools and without distortion of the container or its cover; and to provide a container hav in an external annular rib and a cover for said container having an annular groove adapted to engage the rib of the container to form an air tight joint.

l/Vith the foregoing and other objects in View, my invention consists in certain novel features of construction and arrangements of parts hereinafter more fully described and claimed, and illustrated in the accompany` ing drawings, in whichother' hand.

Figure 1" is la top plan view of the con-v tainer with the cover thereon.

Figure 2 is a vertical: cross-section taken on the line 2 2 of Figure l1.

Figure 3 is a bottom view of the cover.

Figure 4 is a plan view lof the container with the cover removed. j

v' Figure 5*v is an enlarged detail view.l on line 5 5. of Figure. 1.

Referring bynumerals to the accompany@ ing drawings, l0 is the container of circular shape and having lan upwardly extending annular wall 1'1. lThis wall is provided lwith a horizontal annular `flange 12, which is formed *by pressing a portion of wall 11l outwardly and then pressing the upper and lower walls A and B of saidportion towards eachother lso that portion lof wall 11 is refolded and pressed together4 to form ananvnular `flange which reinforces the vwall of said container and provide suitable means vto be gripped by the fingers of one'liand whilefthe cover is.` being removed the In order to st'iffen and strengthen horizonftal'fiange 12 an annular shoulder orrib 14, l' which isV curved in cross-section, is pressed' outwardly from' wall llimmediately below said flange 12. A `similar annular shoulder or rib 15y ispress'ed outwardly ffrom walll l1 immediately above said flange. Annular ribs 14 and 15 reinforce wall 1 1 and horizontal flange' 12 by forming'a rigid connection between said wall and flange. The outwardly projecting annular vrib 15 cover 16. Cover 16 has an annular flange 17 adapted to engage the wall 11 of container 10 and terminating in an annular groove 18 which is adapted to receive the rib 15. Cover 16 is provided with diametrically disposed grips or lugs 19. These grips 19 are integralV with said covering and are formed by making the blank of the ioo cover with outwardly projecting compara-f tively narrow strips which, when the cover is shaped, are bent outwardly at right angles to flange 17 so as to provide horizontal bottom portions 19a and then outwardly .to form vertical outer walls 19b and are then bent downwardly and inwardly so that the ends 19e bear against the vertical walls 19" while the curved portion 19d bears against the flange 17 of said'cover 16. This particular construction provides grips or lugs which can be conveniently gripped by the fingers of one hand in order to remove the cover, and which are of strong and durable construction and are not distorted or bent by strains or pressures applied to them when removingthe cover. The co-operation of curved annular groove 18 o n cover 16 provides efficient connection between said container and cover, which connection' is air tight, thereby preserving andprotecting the contents of the container and preventing Vthe sticking or binding of the cover.

In order to remove the cover, the container is held between the fingers of one hand and preferably at points at right angles to lugs or grips'l9, while said lugs are graspedV between rthe fingers of the other hand. In this manner, the container can be conveniently grasped while the cover is being removed.

^ Obviously my invention permits of various modifications without departing from the spirit thereof, and I do not wish to be limited to the specific construction described.

`lNhat I claim is:

l. A metallic container having an .outwardly projecting annular flange and annular reinforcing beads pressed outwardly above and below said flange at the points of junction of saidvflange with the wall of the `container, and a cover therefor provided with an annular groove-adapted to engage the upper one of said beads and having op- ".positely disposed lugs formed integral with said cover and adapted to overhang the flange of said container.

2'. In combination with a metallic container having a wall provided withan outwardly proj ectingl peripheral. flange-and` an annular rib formed above said flange, of a cover for said container having a. depending flange terminating in an inwardly disposed V`groove which is adapted to engage the rib on said container and projections on said www vcover formed by bending and rebending extensionsonsaidcover whereby sai-d projecflange terminating in an inwardly disposed groove adapted to engage the upper one of said ribs when the cover is in position and diametrically disposed lugs formed by folding and refolding upon themselves portions projecting from the fiange of said cover whereby said lugs proj ect outwardly past the flange on the container, said lugs having outer walls adapted to be gripped between vthe fingers and inner walls bearing against the flan `e of said cover, the endsofy said portions being bent inwardly and outwardly to rest against the outer-walls of said lugs.

4. In combination with a metallic container having an outwardly projecting rib circumferentially disposed on the wall thereof, of a cover having a depending flange terminating in a circumferential groove arranged to co-operate with the rib on said containerto-form an air tight joint, and oppositely disposed-projections on said cover adapted, when said cover is in position, to overhang the fiange of the container, said projections being formed by rebending strips projecting from and formed integral with the fiange of said cover, whereby the ends of said strips bear against the outer portions of said projections and the inner portions bear against the fiange on the cover.

.In testimony whereof I' hereunto aflixmy signature this 3rd day of November,-l920.
